Abstract: 600,637. Toasters. PAGE, H. E. Oct. 4, 1945, No. 25874. Convention date, Oct. 17, 1944. [Class 28(i)] [Also in Group XI] An electric toaster comprises an element in a casing 11 which constitutes a toasting compartment open at one end and at the bottom and pivotally mounted on a base 5 at one corner 20 for upward swinging. Automatic ejector mechanism comprises a bi-metallic strip 63 which can trip a trigger 47 restraining a spring-loaded plunger 41 having two arms 44 each extending into one of two toasting compartments, the resulting movement causing a collar 45 on the plunger to impinge against a ring 46, the vibration thus set up dislodging any toast particles from the heating elements. The bi-metallic strip 63 carries a switch contact 60, cooperating with a contact 61 on a resilient arm 64, and separating when the ejector is tripped. The ejector is adjustable by a control knob 73 actuating a cam 77 bearing on the bi-metallic strip and, after operation, is reset by a knob 86.

Title: Improvements in or relating to tension control apparatus for textile webs
Inventor: FINLAY-MAXWELL DAVID
IPC: G05D15/01
Filed: 1969-05-21
Abstract: 1277087 Automatic tension control JOHN GLADSTONE & CO (ENG) Ltd 21 May 1970 [21 May 1969] 25893/69 Heading G3R [Also in Division D1] The number of weft threads per unit length of a textile web is measured and compared with a desired value so that any difference is effective to restore the number to the desired value by varying web tension. As shown, the number of weft threads per unit length of a knitted or woven web 1 moving towards a winding roll (not shown) is determined from the frequency of the output of, e.g., a photo-transistor 8 responsive to light passing through the web, and the speed of the web as determined by a tachometer 13 driven by a drum 4 round which the web passes. A control unit 11, involving a variable frequency oscillator, effects the calculation and compares the number with a desired number determined by the setting of a device 14 so that any difference, after filtering and amplification, energizes either a magnetic clutch 23 to couple an electric motor 24 to drum 4, or a magnetic clutch 25 to brake the drum according to whether tension requires to be decreased or increased. A tension detector 5, associated with web loops, operates a transducer 20 to produce a tension signal which is compared by control unit 11 with a desired tension signal determined by the setting of a device 21 so that errors exceeding predetermined limits control the clutches 23, 25 as necessary to restore the tension between the limits. The latter control is in addition to or instead of the thread count control which may be disabled by operation of a selector. The desired tension may be automatically increased with (a) increase of web thickness (b) increase of web speed or thickness as detected by transducers 13 or 29 or (c) increase of wind-up roll size as determined by a detector (not shown) applying a signal at 22.

The process is applicable to dyeing, developing and fixing dyestuffs, e.g. in printing, using anthraquinone, indigoid, sulphur dyestuffs, Naphthols, basic, substantive and acetate dyestuffs, acid and chrome dyestuffs, and pigments requiring resins or starches for their fixation; and also bleaching, washing and cleaning fabrics.  Apparatus comprises a series of vessels 1 provided with an inner wall 3 shaped to form spaced wells 4 having vertical parallel walls 7.  The wells are of gradually increasing height from the inlet end of each section, as shown, and each well is provided with a baffle 16 having a guide roller 6 at its lower end.  The baffles are of a thickness to provide a relatively narrow passageway between the baffle and the wall of the well.  Rollers 20 guide the fabric from one well to the next.
